Document Type and Number:
WIPO Patent Application WO/2018/000954
Kind Code:
A1
Abstract:
A power drive system, comprising: an engine (4); first and second input shafts (11,12), the engine (4) being selectively engaged with at least one of the first and second input shafts (11,12); a plurality of output shafts (21, 22), one of the plurality of output shafts (21, 22) being sheathingly provided with a reverse gear output gear (8) and being provided with a reverse gear synchronizer (6c) for connecting the reverse gear output gear (8); a reverse gear shaft (89) on which a first gear of reverse gear shaft (81) and a second gear of reverse gear shaft (82) are fixedly disposed, the first gear of reverse gear shaft (81) being engaged with a gear driving gear which is closest to the reverse gear output gear from among a plurality of gear driving gears on the first input shaft (11), and the second gear of reverse gear shaft (82) being engaged with the reverse gear output gear (8); a motor power shaft (3), the motor power shaft (3) being sheathingly provided with a first gear of motor power shaft (31) and a second gear of motor power shaft (32), the second gear of motor power shaft (32) being configured to move concomitantly with one of the plurality of gear driving gears; and a first motor generator (51), the first motor generator (51) being configured to move concomitantly with the motor power shaft (3). Also provided is a vehicle using the power drive system. The power drive system and vehicle using the same may provide a plurality of forward gears, which ensures smoother power transmission and high transmission efficiency.
